the instructions that came with it are a joke. they should be ashamed of themselves for doing that. but...the machine is incredible. saves me hours and labor. works sooooo fast. I use it to slice beef and chicken for shawarma on the grill. the clear plastic cover is that type of plastic that probably won't be durable but the rest of the machine is so excellent. watch a few youtube videos to learn how to remove the blades as a whole group. be very careful, it's super sharp and I would not let just anyone use it. there is no sort of guards. see pics to understand. just be careful. it's easier to clean that way. two allen screws and a reverse thread knob and it comes apart easily. if mine dies, I will certainly buy another one.UPDATE-the above still holds true. However, customer service is a big ZERO. I attempted to contact vevor two times through their website for an option on replacement blades and they never responded. This is the price you pay for buying cheap instead of from a local dealer. Oh well, next time I know better.
